Four Green Fields at 3518 Conowingo Road sits on Route 136 in Street, Maryland — a rural Harford County community tucked between Jarrettsville and the Mason-Dixon line, where rolling farmland and Deer Creek define the landscape more than strip malls or highway interchange commerce. It’s one of the few dispensaries serving the northern Harford County countryside, and its placement on Conowingo Road makes it a natural stop for residents of Street, Pylesville, Jarrettsville, Delta, and communities stretching toward the Pennsylvania border. A native Maryland family-owned and operated business built on four pillars — Compassionate Care, Empowerment, Wellness, and Inspiration — Four Green Fields has invested heavily in patient education since opening, running a podcast, blog, video library, and cartridge troubleshooting resources alongside its retail floor. The first hour of every operating day is reserved exclusively for medical patients and caregivers. Online pre-ordering is available for both the medical and adult-use menus through the dispensary’s own ordering platform. Beyond cannabis, Four Green Fields sponsors Beach Tennis Maryland, extending its community presence into the region’s active lifestyle scene. Four Green Fields suits recreational adults and medical patients across rural Harford County — Street, Jarrettsville, Pylesville, Bel Air, Darlington, and communities along the Maryland-Pennsylvania border — who want a values-driven, education-first independent dispensary on Conowingo Road.
